EdStainless, I read one of your previous posts talking about Charpys when I searched to see if my question had already been answered. Nice tool to add to my bag of tricks...
MagBen, I think you're right on track. Overlapping hardness with condition A should have been an obvious clue but I...
Yep, the same requirement is in MIL-H-6875. So why does 6875 require tensile testing for the 1100-1150 aged conditions?
And while we're at it, why does 6875 require tensile tests for parts that are resolution annealed? 2759 says tensile tests are required for resolution annealed parts when...
AMS2759/3 paragraph 4.1.1 requires tensile tests for 17-4PH aged from 1100F to 1150F. Hardness testing is sufficient for other aged conditions.
Why? What tensile test properties may vary in these conditions?
Thanks!
